This is the related code fragment where I can't print out the values from valuebox. May I know what's the problem?
public GuaranteedDefsAnalysis(UnitGraph graph)
{
super(graph);
DominatorsFinder df = new MHGDominatorsFinder(graph);
unitToGenerateSet = new HashMap<Unit, FlowSet>(graph.size() * 2 + 1, 0.7f);
// pre-compute generate sets
for(Iterator unitIt = graph.iterator(); unitIt.hasNext();){
Unit s = (Unit) unitIt.next();
FlowSet genSet = emptySet.clone();
for(Iterator domsIt = df.getDominators(s).iterator(); domsIt.hasNext();){
Unit dom = (Unit) domsIt.next();
for(Iterator boxIt = dom.getDefBoxes().iterator(); boxIt.hasNext();){
ValueBox box = (ValueBox) boxIt.next();
box.getValue().toString(); // simply using toString does not work
if(box.getValue() instanceof Local)
genSet.add(box.getValue(), genSet);
}
}
unitToGenerateSet.put(s, genSet);
}
doAnalysis();
}
Can you maybe rephrase your question? What do you mean by "does not work"? Did you forget to add the println statement maybe?

I am currently trying to get list of all dates in a flowfile between the two dates specified using ExecuteScript. But I am somehow getting empty attribute.
Following is my Groovy code of ExecuteScript for the specified startdate and enddate variable specified:
flowFile = session.get();
if(!flowFile)
return;
DATE_FORMAT = 'dd-MM-yyyy';
startDate = Date.parse(DATE_FORMAT, flowFile.getAttribute("startdate"));
endDate = Date.parse(DATE_FORMAT, flowFile.getAttribute("enddate"));
allDates = "";
Calendar calendar = Calendar.getInstance();
Set allDates = new LinkedHashSet();
numbers = TimeUnit.MILLISECONDS.toDays(Math.abs(endDate - startDate))
for (int i = 1; i <= numbers; i++) {
calendar.setTime( startDate );
calendar.add( Calendar.DATE, i );
}
days.each {
day -> allDates = allDates + day + "\n";
}
flowFile = session.putAttribute(flowFile,"allDates", allDates );
session.transfer(flowFile,REL_SUCCESS)
On my outgoing queue I find the attribute allDates is empty String
What is going wrong with my code?
you have some problems in your code
for example the variable allDates declared twice i two different scopes:
global (without type or def)
allDates = "";
and local (with type)
Set allDates = new LinkedHashSet();
after that it's hard to predict which one is used
and actually code could be easier in groovy:
def DATE_FORMAT = 'dd-MM-yyyy';
def startDate = Date.parse(DATE_FORMAT, '01-11-1970');
def endDate = Date.parse(DATE_FORMAT, '09-11-1970');
def allDates = ""
for (def d = startDate; d<=endDate; d++){
allDates+=d.format(DATE_FORMAT)+"\n"
}
println allDates
note that this is runable code so you can use groovyconsole or any IDE to debug it before integrating into nifi
of cause you have to wrap it with flow file handling before using in nifi
I am new to SoapUi. I am exploring on how multiple request in soapUi is done using groovy script.
below is the example that im trying to do, based on example that i found through "googling"
import com.eviware.soapui.SoapUI;
import com.eviware.soapui.model.testsuite.*;
import com.eviware.soapui.impl.wsdl.testcase.WsdlTestCaseRunner
import java.util.Random
import com.eviware.soapui.model.testsuite.TestRunner.Status
// Define your testCase pointer
//def testcase = testRunner.testCase.testSuite.project.testSuites["TestSuite - User Management REST API"].getTestCaseByName ("Authenticate User")
def counterUser = testRunner.testCase.testSuite.getPropertyValue( "counter" )
int value = counterUser.toInteger()
String tester = ""
30.times {
value = value + 1
tester = "tester " + value.toString()
testRunner.testCase.testSuite.setPropertyValue( "userName", tester )
testRunner.runTestStepByName("POST - createUser - Create a User")
}
testRunner.testCase.testSuite.setPropertyValue( "counter", value.toString() )
I want to create a 30 users which start from Tester1...tester2.....tester30.
Is it possible to do this way? I keep getting an error such as NullPointerException at this line
int value = counterUser.toInteger()
I got what you say.
That is because, initially there is no value for counter which results to null and you are applying toInteger() over it.
Just change:
From:
int value = counterUser.toInteger()
To:
int value = counterUser?.toInteger() ?: 0
I am fairly new to the Groovy/Grails arena. I recently modified some code to add the following block.
result.processed.each{
def queueEntry = QueueEntry.findById(it.id)<<<START ADD>>>
Set dates = new HashSet<Long>()
def children = QueueEntry.findAllByParent(queueEntry)
for(QueueEntry qe : children){
def f = new GregorianCalendar()
f.setTimeInMillis(DateUtils.getClearedTime(qe.entryTimestamp))
def l = new GregorianCalendar()
l.setTimeInMillis(DateUtils.getClearedTime(qe.exitTimestamp))
while(f < l){
if(f.get(Calendar.DAY_OF_WEEK) != Calendar.SUNDAY && f.get(Calendar.DAY_OF_WEEK) != Calendar.SATURDAY){//only add weekdays
dates.add(f.time.time)
}
def xx = new GregorianCalendar()
xx.setTimeInMillis(f.time.next().time)
f = xx
}
dates.add(l.time.time)
} <<<STOP ADD>>>
Set outsideDays = it.numberOfDaysOutsideCVB
Set days = DateUtils.businessDaysBetweenDates(it.entryTimestamp, it.exitTimestamp)
days.removeAll(outsideDays)
days.removeAll(dates)
turnTimes << days.size()
}
The application is now crawling. I am obviously doing something wrong. When this is run for small data-sets it will complete slowly. On larger sets it doesn't finish. Prior to this change it was completing.
You can start with the lines of the below changes.
// Proposed
import static java.util.Calendar.*
// Query for all the children upfront instead of hitting
// database twice on each iteration.
// You can also avoid N + 1 situation if children is fetched eagerly
def allChildren = QueueEntry.where {
id in (result.processed*.id as List<Long>)
}.children.list()
def turnTimes = result.processed.collect { entry ->
allChildren.findAll { it.parent.id == entry.id }.collect { child ->
Set dates = []
new Date( child.entryTimeStamp ).upto( new Date( child.exitTimestamp ) ) {
if ( !( it[DAY_OF_WEEK] in [ SUNDAY, SATURDAY ] ) ) {
dates << it.time
}
}
Set outsideDays = child.numberOfDaysOutsideCVB
Set days =
DateUtils.businessDaysBetweenDates(
child.entryTimestamp,
child.exitTimestamp
)
( days - outsideDays - dates )?.size() ?: 0
}
}
Assumptions:
QueueEntry hasMany children
entryTimestamp/exitTimestamp is java.sql.Timestamp
entryTimestamp/exitTimestamp are not null and entryTimestamp comes before exitTimestamp.

I am new to Groovy and I could not get around this issue. I appreciate any help.
I want to read a file from Groovy. While I am reading the content, for each line I want to substitute the string '${random_id}' and '${entryAuthor}' with different string values.
protected def doPost(String url, URL bodyFile, Map headers = new HashMap() ) {
StringBuffer sb = new StringBuffer()
def randomId = getRandomId()
bodyFile.eachLine { line ->
sb.append( line.replace("\u0024\u007Brandom_id\u007D", randomId)
.replace("\u0024\u007BentryAuthor\u007D", entryAuthor) )
sb.append("\n")
}
return doPost(url, sb.toString())
}
But I got the following error:
groovy.lang.MissingPropertyException:
No such property: random_id for class: tests.SimplePostTest
Possible solutions: randomId
at foo.test.framework.FooTest.doPost_closure1(FooTest.groovy:85)
at groovy.lang.Closure.call(Closure.java:411)
at groovy.lang.Closure.call(Closure.java:427)
at foo.test.framework.FooTest.doPost(FooTest.groovy:83)
at foo.test.framework.FooTest.doPost(FooTest.groovy:80)
at tests.SimplePostTest.Post & check Entry ID(SimplePostTest.groovy:42)
Why would it complain about a property, when I am not doing anything? I also tried "\$\{random_id\}", which works in Java String.replace(), but not in Groovy.
You are doing it the hard way. Just evaluate your file's contents with Groovy's SimpleTemplateEngine.
import groovy.text.SimpleTemplateEngine
def text = 'Dear "$firstname $lastname",\nSo nice to meet you in <% print city %>.\nSee you in ${month},\n${signed}'
def binding = ["firstname":"Sam", "lastname":"Pullara", "city":"San Francisco", "month":"December", "signed":"Groovy-Dev"]
def engine = new SimpleTemplateEngine()
template = engine.createTemplate(text).make(binding)
def result = 'Dear "Sam Pullara",\nSo nice to meet you in San Francisco.\nSee you in December,\nGroovy-Dev'
assert result == template.toString()
you better use groovy.text.SimpleTemplateEngine class; check this for more details http://groovy.codehaus.org/Groovy+Templates
The issue here is that Groovy Strings will evaluate "${x}" by substituting the value of 'x', and we don't want that behaviour in this case. The trick is to use single-quotes which denote plain old Java Strings.
Using a data file like this:
${random_id} 1 ${entryAuthor}
${random_id} 2 ${entryAuthor}
${random_id} 3 ${entryAuthor}
Consider this code, which is analogous to the original:
// spoof HTTP POST body
def bodyFile = new File("body.txt").getText()
StringBuffer sb = new StringBuffer()
def randomId = "257" // TODO: use getRandomId()
def entryAuthor = "Bruce Eckel"
// use ' here because we don't want Groovy Strings, which would try to
// evaluate e.g. ${random_id}
String randomIdToken = '${random_id}'
String entryAuthorToken = '${entryAuthor}'
bodyFile.eachLine { def line ->
sb.append( line.replace(randomIdToken, randomId)
.replace(entryAuthorToken, entryAuthor) )
sb.append("\n")
}
println sb.toString()
The output is:
257 1 Bruce Eckel
257 2 Bruce Eckel
257 3 Bruce Eckel
Is it possible to have named parameters with default values in groovy? My plan is to make a sort of object factory, which can be called with no arguments at all in order to get an object with default values. Also, I'd need the functionality to explicitly set any of the params for the object. I believe this is possible with Python keyword arguments, for example.
The code I'm attempting with right now is something like below
// Factory method
def createFoo( name='John Doe', age=51, address='High Street 11') {
return new Foo( name, age, address )
}
// Calls
Foo foo1 = createFoo() // Create Foo with default values
Foo foo2 = createFoo( age:21 ) // Create Foo where age param differs from defaut
Foo foo3 = createFoo( name:'Jane', address:'Low Street 11' ) // You get the picture
// + any other combination available
The real app that I'm working on will have a lot more of parameters and thus a lot more combinations needed.
Thanks
UPDATE:
The factory method I'm planning is for testing purposes. Cannot really touch the actual Foo class and especially not it's default values.
#dmahapatro and #codelarks answere below had a good point in using a Map as a param that gave me an idea of a possible solution. I could create a map with the wanted defaults and override the needed values, and pass that to the factory method. This'll probably do the job and I'll go with that, unless I get a hint of a better approach.
My current approach below
defaults = [ name:'john', age:61, address:'High Street']
#ToString(includeFields = true, includeNames = true)
class Foo {
// Can't touch this :)
def name = ''
def age = 0
def address = ''
}
def createFoo( Map params ) {
return new Foo( params )
}
println createFoo( defaults )
println createFoo( defaults << [age:21] )
println createFoo( defaults << [ name:'Jane', address:'Low Street'] )
NOTE: leftShift operation ( << ) modifies the the original map, so in the above example age will be 21 in the last method call as well. In my case, this is not a problem as the defaults map can be created freshly each time in setup method.
Groovy does that for you by default (map constructor). You would not need a factory method. Here is an example
import groovy.transform.ToString
#ToString(includeFields = true, includeNames = true)
class Foo{
String name = "Default Name"
int age = 25
String address = "Default Address"
}
println new Foo()
println new Foo(name: "John Doe")
println new Foo(name: "Max Payne", age: 30)
println new Foo(name: "John Miller", age: 40, address: "Omaha Beach")
//Prints
Foo(name:Default Name, age:25, address:Default Address)
Foo(name:John Doe, age:25, address:Default Address)
Foo(name:Max Payne, age:30, address:Default Address)
Foo(name:John Miller, age:40, address:Omaha Beach)
UPDATE
#codelark's astrology :). In case the class is not accessible to set default values, you can do like
#ToString(includeFields = true, includeNames = true)
class Bar{
String name
int age
String address
}
def createBar(Map map = [:]){
def defaultMap = [name:'John Doe',age:51,address:'High Street 11']
new Bar(defaultMap << map)
}
println createBar()
println createBar(name: "Ethan Hunt")
println createBar(name: "Max Payne", age: 30)
println createBar(name: "John Miller", age: 40, address: "Omaha Beach")
//Prints
Bar(name:John Doe, age:51, address:High Street 11)
Bar(name:Ethan Hunt, age:51, address:High Street 11)
Bar(name:Max Payne, age:30, address:High Street 11)
Bar(name:John Miller, age:40, address:Omaha Beach)
